“…Post ablation, the plasma cools down and depressurizes, leading to cluster growth and the fabrication of desired NPs and nanocrystals. 28 Unlike conventional nanofabrication techniques that require specific control of synthesis parameters such as pressure and temperature, 29 LASiS 17,30 is a simple, nontoxic, environmentally friendly, and cost-effective technique for nanomaterial production. The underlying physicochemical processes that lead to rational synthesis of a broad range of NMs via the LASiS-GRR are presented in our previous publications.…”

Conversion of designer metal−organic frameworks (MOFs) into hybrid nanocomposites (HNCs) consisting of transition metal/metal oxides interfaced with carbon (C) matrices has emerged as a promising and economical alternative for the synthesis of oxygen reduction reaction (ORR) electrocatalysts, owing to their superior conductivity and high porosity. To that end, optimizing the performance of this class of material by tailoring its composition, structure, size, and morphology through an efficient synthesis route has become an active area of research. Specifically, this study employs Laser Ablation Synthesis in Solution in tandem with Galvanic Replacement Reaction (LASiS-GRR) technique as an environmentally friendly, facile, and rapid route for the design and synthesis of core−shell bimetallic zeolitic imidazolate framework (ZIF) heterostructures as bi-MOFs, and then uses pyrolytic postprocessing to yield hierarchical metal oxide/MOF-based functional HNCs as highly active ORR electrocatalysts. The LASiS-GRR technique employs high-energy laser plasma reactions as the ratecontrolling step for initiating solution-phase galvanic reactions. The one-pot, two-step process introduced in this study enables tailoring of the composition, structure, size, and morphology of composite bi-MOFs comprising Co-based MOFs encapsulated in Zn-based porous crystals (Co/ZIF-67@Zn/ZIF-8). Pyrolytic postprocessing of these core−shell bi-MOF crystals leads to the creation of hierarchical ZnO@ZIF/C HNCs with superior ORR electrocatalytic performances under alkaline conditions. Overall, these findings not only elucidate the process by which LASiS-GRR protocols are optimized to tailor the morphology, structure, and composition of complex MOF structures but also demonstrate the superior performance and stability of the ensuing postpyrolyzed ZnO@ZIF/C HNCs as nonprecious metal-based ORR electrocatalysts, when compared to commonly used Pt-and Pt-group metal (PGM)-based electrocatalysts.

The synergistic union of nanomaterials with biomaterials has revolutionized synthetic chemistry, enabling the creation of nanomaterial-based biohybrids with distinct properties for biomedical applications. This class of materials has drawn significant scientific interest from the perspective of functional extension via controllable coupling of synthetic and biomaterial components, resulting in enhancement of the chemical, physical, and biological properties of the obtained biohybrids. In this review, we highlight the forefront materials for the combination with biomacromolecules and living organisms and their advantageous properties as well as recent advances in the rational design and synthesis of artificial biohybrids. We further illustrate the incredible diversity of biomedical applications stemming from artificially bioaugmented characteristics of the nanomaterial-based biohybrids. Eventually, we aim to inspire scientists with the application horizons of the exciting field of synthetic augmented biohybrids.

Herein, we report the expedient synthesis of new nanocomposite Sn0.39Ti0.61O2·TiO2 flakes using simple sol–gel and calcination methods. In order to prepare this material, first, we generated a polymeric gel using cost-effective and easily accessible precursors such as SnCl4, titanium isopropoxide, and tetrahydrofuran (THF). A small amount of triflic acid was used to initiate THF polymerization. The calcination of the resulting gel at 500 °C produced a Sn–Ti bimetallic nanocomposite. This newly synthesized Sn0.39Ti0.61O2·TiO2 was characterized by X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and UV–visible spectroscopy. The photoelectrochemical (PEC) studies were performed for the first time using Sn0.39Ti0.61O2·TiO2 coated over fluorine-doped tin oxide (FTO) under simulated 1 sun solar radiation. The chronoamperometric study of the Sn0.39Ti0.61O2·TiO2/FTO revealed the repeatable and substantially higher photocurrent for the oxygen evolution reaction (OER) when compared to only TiO2. Moreover, the synthesized material exhibited high stability both in the presence and absence of light. The photocatalytic studies suggested that the sol–gel-synthesized Sn0.39Ti0.61O2·TiO2 can be efficiently used as a photoanode in the water-splitting reaction.
